[Tear_15] Ramp lesion -01

Medial meniscus is firmly attached to the tibia and femur, acting as a knee stabilizer, and preventing anterior translation, especially in the ACL-deficiency.

Ramp lesions, whose name reflects the ramp-like appearance of the posteromedial zone, are a particular type of injury within the posterior horn of the medial meniscus and its meniscocapsular attachments.

To date, there is no consensus regarding the definition of a ramp lesion.
Meniscal ramp lesions can be defined as longitudinal vertical and/or oblique peripheral tears in the posterior horn of medial meniscus, in a mediolateral direction of less than 2.0 cm, that may lead to meniscocapsular or meniscotibial disruption with a concomitant ACL injury

While various authors have differing definitions of what constitutes a “ramp lesion,” most include meniscocapsular separation and meniscosynovial tears, with variable inclusion of tears of the red-red zone of the peripheral posterior horn or junction of the posterior horn and body.
